Forensic Eye Exams in Seattle, WA

Dr. Mark Cannon provides forensic eye exams to determine the extent and limitations of an individual’s vision. This exam type must be set up between a law office and Dr. Mark directly. It is noteworthy that not all cases will be accepted.

Forensic eye exams may be helpful in personal injury cases, criminal cases, or any legal case where there may be a question about what a party or witness was able to see. Dr. Mark is available for forensic eye exams on behalf of plaintiffs or defendants in civil cases, or for the defense or prosecution in criminal cases.

Book an Eye Exam

Forensic eye exams are a crucial, yet often overlooked, part of modern crime investigation and forensic science. Whether you’re a job applicant preparing for a forensic position, a medical professional expanding your skills, or simply curious about how eyes play a role in solving crimes, this guide will walk you through everything you need to know.

What Is a Forensic Eye Exam?

A forensic eye exam is a specialized assessment of the eyes, conducted to gather evidence for legal investigations. Unlike a standard eye check-up, forensic exams focus on identifying unique features, injuries, or diseases that can provide clues about a crime, accident, or cause of death.

Why is it important?

  • Postmortem investigations: Eye findings help estimate the time of death and identify trauma or poisoning.

  • Criminal identification: Eyewear and contact lenses can link suspects to crime scenes.

  • Job Requirements: Many forensic careers require applicants to pass a visual acuity or pattern recognition test.

Forensic eye exams are not just about vision—they’re about using the eye as a source of evidence in legal cases.

How Is a Forensic Eye Exam Conducted? (Step-by-Step Guide)

Forensic eye exams follow a systematic approach to ensure accuracy and reliability. Here’s a step-by-step breakdown of what happens during the exam:

  1. Patient History and Consent

    • Review medical history and explain the procedure.

    • Obtain informed consent, especially for invasive tests.

  2. Visual Acuity Testing

    • Use a Snellen or Rosenbaum chart to measure clarity of vision.

    • Test each eye separately, with and without correction.

  3. Visual Field Assessment

    • Check peripheral vision using confrontation or formal field testing.

  4. Color Vision and Contrast Sensitivity

    • Assess color perception (e.g., Ishihara test).

    • Evaluate contrast sensitivity if needed.

  5. External Eye Examination

    • Inspect eyelids, lashes, conjunctiva, cornea, and iris.

    • Look for injuries, foreign bodies, or abnormalities.

  6. Pupillary Reflexes and Accommodation

    • Test pupil reaction to light and near objects.

    • Assess for neurological abnormalities.

  7. Fundoscopy and Advanced Imaging

    • Examine the retina and optic nerve using an ophthalmoscope.

    • Use advanced imaging (OCT, infrared) for detailed analysis if required.

Tip:
Practice with sample eye charts and pattern recognition tests to prepare for forensic job exams.
